Even if they play the different API game, that just means... whoever has the easier and faster API wins. It also means you don't have to pay for an 8-core processor. Current quads are still going for $300, while their duals equivalence are $150 - 200. How much do you think an 8-core processor will be when it comes out? (And by the way, the estimated price tag scares me...)

so either your CPU is going to be expensive, or your GFX card is going to be expensive...

price is irrelevant, as either way, its going to be expensive.


and another reason its better to have an 8 cored-processor vs GPU-based physics is because the extra cores don't have to be used specifically for physics, whereas having the GPU preform physics calculations would limit it's power specifically for physics.

you won't be transfering GBs of data

if there was that much data being transformed, it would be slow regardless.

and data still has to be transfered within the GPU as well...
The GPU has its own Bus to transfer information between it's processors and memory.
its faster than from CPU -> GPU, but its still not instantaneous.


and a physics processor would be faster than a general-purpose processor at physics, but thats all it would be good for.
